Title: Manufacture of gaas semiconductor substrate
Inventor: AIGOU TAKASHI
IPC: H01L29/812
Filed: 1985-10-07
Abstract: PURPOSE:To enhance the adhesion (bonding strength) of a bonding pad and a GaAs substrate, by adding a metal layer between a conventional film of Ti/Pt/Au and the GaAs substrate, and forming an alloy layer of the gold layer and the GaAs substrate. CONSTITUTION:A gold layer 10 is formed beneath a conventional gold plated layer 8 and a three-layer film 9 of Ti/Pt/Au. Heat treatment is performed so that ohmic contact of a source electrode 1 and a drain electrode 2, which have been formed before, is obtained with respect to the GaAs active layer. At the same time, the alloy layer of the gold layer 10 and the GaAs substrate 6 is obtained by this heat treatment. The heat treatment is performed by mounting the GaAs substrate 6 on a heat block, which is heated to 450 deg.C for 2min. By implementing the alloy from the gold layer 10 and the GaAs substrate 6, the bonding strength (adhesion) of the bonding pad 4 and the GaAs substrate 6 is enhanced.

Title: Input buffer circuit
Inventor: SHIRAI TAKAYUKI
IPC: H03K3/3565
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To make the input buffer circuit stably operate without causing malfunction by setting a final output transition period where a power line noise is generated most easily for hysteresis circuit operation. SOLUTION: When transistors(TR) P1 and P2 turn on and the output 1 of a detecting circuit 19 detects a transition state, a low pulse of the output 1 is generated in a specific period and at this time, a TR P3 turns on, so that the logical threshold value of an input initial stage becomes high. Then when an input Ai varies from a low level to a high level, TRs N1-N3 turn on in a specific time and then the initial stage logical threshold value becomes low. Thus, the delay width of a delay circuit is set so that final data output transition is caused in a specific time and then an input buffer circuit is made to effectively operate as a hysteresis circuit. Namely, the final data output transition period wherein a power source noise is generated most easily is included in the specific time to prevent malfunction due to the power line noise of the input buffer.

Title: Material for casting mold
Inventor: HASEGAWA MASAE
IPC: B22C1/00
Filed: 1986-09-19
Abstract: PURPOSE:To eliminate the need for a mold coating operation and casting mold drying stage and to reduce the cost of manufacturing castings by constituting aggregate of flaky graphite and molding sand and specifying the compounding ratio thereof. CONSTITUTION:The compounding ratio of the aggregate constituted of the aggregate and a binder is so specified as to consist of 5-99wt.% flaky graphite and a binder the balance, i.e., 1-95wt.% molding sand. The compounding ratio of the binder is so specified that a resin is incorporated into the aggregate within the range of 1-10wt.% of the aggregate and a curing reaction liquid of 1-5wt.%. The reason for limiting the compounding ratio of the aggregate lies in that the amt. of the resin to be added needs be increased if the content of the flaky graphite is 100wt.%. Combustion gas increases and blow holes are generated in such a case. Burn-on is not preventable if the content of the molding sand is 100wt.%.

Title: Method and device for detecting engine-nock-strength signal
Inventor: POCKSTALLER FRANZ
IPC: G01L23/16
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To detect a highly reliable knock strength signal even after long time use by employing the first passage of electrical light signal for producing an engine knock strength signal. SOLUTION: Light sampled by a photosensor 1 is transmitted through an optical guide 6 to a photoelectric converter 11 (e.g. a photodiode) where it is converted into an electric light signal. The electric light signal is amplified by an amplifier 12 and delivered to a low-pass filter 13. The low-pass filter 13 serves such that the higher frequency in electric light signal causes only a small scanning miss in the following operation for digitizing the electric light signal through an A/D converter 14. The digitized electric light signal finally arrives at a digital evaluation unit 15. The unit 15 detects a knock strength signal under formation of first passage of electric light signal.

When the error is smaller than a designated threshold value, the current mapping consisting of the minimum variables a, b is coded. When the error is larger than the designated threshold value, the block is divided into sub area blocks, and the process above is repetitively applied to each sub area block.
